This is on the verge of being over my head, but I'm willing to speculate...

I know what a USB hub is, I have an exernal one. It is safe to assume they are used internally in the computer, rather than committing one I/O space address to each physical USB port. That's reasonable.

Plug it in manually? Do you mean to plug it in to the same physical USB port every time?

In windows, pull up the START->CONTROL PANEL->SYSTEM->HARDWARE MANAGER and expand PORTS.
[[ I've had my nose pretty deep into various parts of this OS over the last month, getting it set up the way I want it.]]

It's called "Device Manager" in Vista and there are no "Ports" unless you add(install) them into Device Manager. I assume this is installing a driver (from cabinet file), which isn't needed without a real Serial port.
The HELP sort of implies that these are only for hardware serial ports - none here.

Perhaps one "Port" will appear (in Device Manager) when the adapter is plugged in, but the Device Manager instructions *seem* to say that the "Ports" category is only for Real, RS-232 Serial Ports.

This laptop has 4 USB ports on the sides. I could see that a USB Hub is probably used for internal devices. like the Modem as you say.

The Device Manager shows:
_eight_ USB Universal Host Controllers,
numbered 2934-293C (skip B)
One "USB Composite Device"
_eight _ USB Root Hub"s

The properties of none of these shows anything like a port number.

It's critical because on two of the radios (706 & TH-F6A) I steal power from
the serial port for the level conversion circuitry.
